Cookie, from English COOKIE (English: 'kuki yin: 'kukɪ), is a Cantonese transliteration from Hong Kong, cookies are interpreted in the United States and Canada as small and flat egg-shaped biscuits, while English The COOKIE came from German koekje, meaning "small egg tarts." This word is mainly used in British English to distinguish American cookies such as "Chocolate Cookies."

Handmade cookies are one of the most popular foods in the world. Although the different cookies have their own characteristics, their practices are similar. They use water to make the bottom cake as thin as possible and allow bubbles to appear. And after that, a lot of butter and eggs will be added, and then dried to saturate the bubbles and let the small amount of water in the eggs escape. This saturation process creates the most appealing character of cookies, which is a refreshing taste.
